Consider it a convention. Basically, it doesn't make much sense to register many more digits after a digit that is uncertain. Another common convention is to enclose uncertain digits - often the last two digits shown - in parentheses, for example, 6.67384(80)×10−11 for the gravitational constant in SI units.,

What term refers to all the certain digits and one uncertain digit in a measurement?
A term Significant Figure refers to all the certain digits and one uncertain digit in a measurement.
How many significant digit are in the measurement 589.0540 newtons?
All the digits are significant in this case. A zero between other digits is always significant, and all zeros after the decimal point are significant.
The number of significant figures is the measurement 170.040 km is?
170.040 has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
How is precision related to the significant figures in a measured quantity?
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
Are all of the digits in the described measurement of 750 mL singnificant?
Integers ending in 0 are ambiguous cases. The measurement could be accurate to the units digit and in that case all three digits are significant. But is could be accurate to the nearest ten, in which case, only the first two digits are significant.
